Abstract

A surge suppression apparatus including a housing (12) and a flexible diaphragm (14) dividing said housing (12) into first and second sub-chambers (27a, 27b), the first sub-chamber (27a) having connection means (28, 30) for connecting the first sub-chamber to a supply of liquid under pressure, the second sub-chamber (27b) containing a gas under pressure, and, a gas reservoir (16) in communication with the second sub-chamber (27b) so as, in use, to provide an effective volume which is substantially larger than that of the second sub-chamber (27b). <IMAGE>
